Which cell organelle is known as the 'powerhouse of the cell' and contains its own DNA?
Lysosome
Golgi apparatus
Mitochondria
Endoplasmic reticulum
Mitochondria
Mitochondria are widely known as the 'powerhouse of the cell' because they generate most of the chemical energy needed to power biochemical reactions. Furthermore, unlike most other organelles, mitochondria contain their own independent circular DNA.
Mitochondria are widely known as the 'powerhouse of the cell' because they generate most of the chemical energy needed to power biochemical reactions. Furthermore, unlike most other organelles, mitochondria contain their own independent circular DNA.
Mitochondria are like a municipal power plant that burns raw fuel to supply electricity for an entire city's operations.
Mighty Mitochondria Make ATP (Power)
C6тАЛH12тАЛO6тАЛ+6O2тАЛтЖТ6CO2тАЛ+6H2тАЛO+ATP тАФ Cellular respiration equation
Inside the mitochondria, energy from nutrients is converted into adenosine triphosphate (ATP) through cellular respiration, which includes the Krebs cycle and oxidative phosphorylation occurring across the folded inner membrane known as cristae.
Mitochondria have a double-membrane structure consisting of a smooth outer membrane and a folded inner membrane.
They contain their own circular DNA (mtDNA) and ribosomes, which supports the Endosymbiotic Theory.
Mitochondrial DNA in humans is inherited exclusively maternally.
High-efficiency production of ATP enables complex multicellular life and high-energy cellular processes.
Damage or mutations in mitochondrial DNA can lead to debilitating metabolic and degenerative diseases.
High concentrations of mitochondria are found in high-energy demand cells like skeletal muscle cells and neurons.
Option A (Lysosome) functions as the cell's waste disposal and recycling center.
Option B (Golgi apparatus) packages and modifies proteins and lipids for transport.
Option D (Endoplasmic reticulum) synthesizes proteins and lipids.
C is correct тАФ Mitochondria generate ATP via cellular respiration and possess their own distinct DNA.
Keep in mind that both mitochondria and chloroplasts contain their own DNA and 70S ribosomes, which is a favorite topic in competitive exams regarding the Endosymbiotic Theory.
